Software and the social production of disorder

Software development is inherently an ordering process. When implemented in a workplace it orders the ways that people go about their work, the work they do, and the ways they interact and communicate with each other. This new mode of ordering may conflict with existing orders, existing distributions of power and knowledge, and arrangements of groups, and between groups. Ordering is almost always the subject of dispute, so software development can easily become enmeshed in the politicking between competing groups with deleterious effects. Removing all these conflicts may not be possible, as they can be an essential part of the ways relevant groups interact. Better communication, for example, may actually increase conflict, and not produce harmony. Rather than thinking of order and disorder as mutually exclusive polarities, it is more effective and realistic to think of them as constituting an 'order/disorder complex' and to expect disorder to appear alongside the ordering. This paper explores the problems of ordering and disordering through a study of changes in the Australian Customs' "Integrated Cargo System". We suggest that acceptance of some untidied mess, or openness to both dispute and unclarity, may be useful in implementing functional software. © 2010 IEEE

China's economic growth engine: The likely types of hardware failure, software failure and power supply failure

The 6th Plenum of the 16th Central Committee of the Communist Party of China (CPC) concluded on October 11, 2006, with the commitment to establish a harmonious society by 2020. The obvious implication from this commitment is that the present major social, economic and political trends are not leading to a harmonious society or, at least, not leading to a harmonious society fast enough. Analytically, if the Chinese economy is depicted as a speeding car, there are three classes of failures (a) a hardware failure from the breakdown of an economic mechanism, a development that is analogous to the collapse of the chassis of the car; (b) a software failure from a flaw in governance that creates frequent widespread social disorders that disrupt production economy-wide and discourage private investment, a situation similar to a car crash that resulted from a fight among the people inside the speeding car; and (c) a power supply failure from hitting either a natural limit or an externally-imposed limit, a situation that is akin, respectively, to the car running out of gas or to the car smashing into a barrier erected by an outsider. For hardware failure we discuss the possible weakening of China's fiscal position generated by the repeated recapitalization of the state banks. For software failure, we discuss possible social disorder caused by outmoded governance. And for power supply failure, we discuss the possible trade disputes from China’s chronic trade imbalances and the physical constraints posed by China’s rapidly deteriorating natural environment.China; growth; banks; environment

How Much is the Whole Really More than the Sum of its Parts? 1 + 1 = 2.5: Superlinear Productivity in Collective Group Actions

In a variety of open source software projects, we document a superlinear growth of production ($R \sim c^\beta$) as a function of the number of active developers $c$, with $\beta \simeq 4/3$ with large dispersions. For a typical project in this class, doubling of the group size multiplies typically the output by a factor $2^\beta=2.5$, explaining the title. This superlinear law is found to hold for group sizes ranging from 5 to a few hundred developers. We propose two classes of mechanisms, {\it interaction-based} and {\it large deviation}, along with a cascade model of productive activity, which unifies them. In this common framework, superlinear productivity requires that the involved social groups function at or close to criticality, in the sense of a subtle balance between order and disorder. We report the first empirical test of the renormalization of the exponent of the distribution of the sizes of first generation events into the renormalized exponent of the distribution of clusters resulting from the cascade of triggering over all generation in a critical branching process in the non-meanfield regime. Finally, we document a size effect in the strength and variability of the superlinear effect, with smaller groups exhibiting widely distributed superlinear exponents, some of them characterizing highly productive teams. In contrast, large groups tend to have a smaller superlinearity and less variability.Comment: 29 pages, 8 figure

A review of GIS-based information sharing systems

GIS-based information sharing systems have been implemented in many of England and Wales' Crime and Disorder Reduction Partnerships (CDRPs). The information sharing role of these systems is seen as being vital to help in the review of crime, disorder and misuse of drugs; to sustain strategic objectives, to monitor interventions and initiatives; and support action plans for service delivery. This evaluation into these systems aimed to identify the lessons learned from existing systems, identify how these systems can be best used to support the business functions of CDRPs, identify common weaknesses across the systems, and produce guidelines on how these systems should be further developed. At present there are in excess of 20 major systems distributed across England and Wales. This evaluation considered a representative sample of ten systems. To date, little documented evidence has been collected by the systems that demonstrate the direct impact they are having in reducing crime and disorder, and the misuse of drugs. All point to how they are contributing to more effective partnership working, but all systems must be encouraged to record how they are contributing to improving community safety. Demonstrating this impact will help them to assure their future role in their CDRPs. By reviewing the systems wholly, several key ingredients were identified that were evident in contributing to the effectiveness of these systems. These included the need for an effective partnership business model within which the system operates, and the generation of good quality multi-agency intelligence products from the system. In helping to determine the future development of GIS-based information sharing systems, four key community safety partnership business service functions have been identified that these systems can most effectively support. These functions support the performance review requirements of CDRPs, operate a problem solving scanning and analysis role, and offer an interface with the public. By following these business service functions as a template will provide for a more effective application of these systems nationally

Association of a MET genetic variant with autism-associated maternal autoantibodies to fetal brain proteins and cytokine expression.

The contribution of peripheral immunity to autism spectrum disorders (ASDs) risk is debated and poorly understood. Some mothers of children with ASD have autoantibodies that react to fetal brain proteins, raising the possibility that a subset of ASD cases may be associated with a maternal antibody response during gestation. The mechanism by which the maternal immune system breaks tolerance has not been addressed. We hypothesized that the mechanism may involve decreased expression of the MET receptor tyrosine kinase, an ASD risk gene that also serves as a key negative regulator of immune responsiveness. In a sample of 365 mothers, including 202 mothers of children with ASD, the functional MET promoter variant rs1858830 C allele was strongly associated with the presence of an ASD-specific 37+73-kDa band pattern of maternal autoantibodies to fetal brain proteins (P=0.003). To determine the mechanism of this genetic association, we measured MET protein and cytokine production in freshly prepared peripheral blood mononuclear cells from 76 mothers of ASD and typically developing children. The MET rs1858830 C allele was significantly associated with MET protein expression (P=0.025). Moreover, decreased expression of the regulatory cytokine IL-10 was associated with both the MET gene C allele (P=0.001) and reduced MET protein levels (P=0.002). These results indicate genetic distinction among mothers who produce ASD-associated antibodies to fetal brain proteins, and suggest a potential mechanism for how a genetically determined decrease in MET protein production may lead to a reduction in immune regulation

Personality Traits and Coping Strategies for Contrasting the Occurrence of Traumatic Reactions in Emergency Rescuers

We investigated personality traits, coping strategies, and social factors among emergency rescuers of three different catastrophic events that occurred in 2009 and 2013. These events were natural disasters, two of which were caused by human negligence. We used the cognitive interview (CI) protocol to interview witnesses and investigate their memory of the event. A qualitative analysis using the ATLAS.ti software was performed to subdivide the type of verbal production in the number of scenes recollected, negative emotions, vivid mental images, and self-experience of the event. All participants were also assessed using the Trauma Symptom Inventory for the presence of traumatic reactions at the time of the interview and tests (from December 2015 until January 2016) and 6 months before the interview to exclude the presence of further Traumatic job-related events. Personality traits (Big Five Questionnaire), coping strategies (Coping Inventory for Stressful Situations-Adult), and other social factors (the Post-Traumatic Growth Inventory) have been assessed. The aim of the study is to identify individual factors contributing to the development of post-traumatic stress disorder (PTSD) in emergency rescuers. We found that some personality traits, social factors, and specific cognitive strategies may act as protective factors to traumatic reactions

Cultural consequences of computing technology

Computing technology is clearly a technical revolution, but will most probably bring about a cultural revolution\ud as well. The effects of this technology on human culture will be dramatic and far-reaching. Yet, computers and\ud electronic networks are but the latest development in a long history of cognitive tools, such as writing and printing.\ud We will examine this history, which exhibits long-term trends toward an increasing democratization of culture,\ud before turning to today's technology. Within this framework, we will analyze the probable effects of computing on\ud culture: dynamical representations, generalized networking, constant modification and reproduction. To address the\ud problems posed by this new technical environment, we will suggest possible remedies. In particular, the role of\ud social institutions will be discussed, and we will outline the shape of new electronic institutions able to deal with the\ud information flow on the internet

Mom-it helps when youre right here! Attenuation of neural stress markers in anxious youths whose caregivers are present during fMRI.

Close proximity to an attachment figure, such as a caregiver, has been shown to attenuate threat-related activity in limbic regions such as the hypothalamus in healthy individuals. We hypothesized that such features might be similarly attenuated by proximity during a potentially stressful situation in a clinically anxious population of youths. Confirmation of this hypothesis could support the role of attachment figures in the management of anxiety among children and adolescents. Three groups were analyzed: anxious children and adolescents who requested that their caregiver accompany them in the scanner room, anxious children and adolescents without their caregiver in the scanner room and healthy controls (each of N = 10). The groups were matched for age and, among the two anxious groups, for diagnosis (mean age 9.5). The children and adolescents were exposed to physical threat words during an fMRI assessment. Results indicate that activity in the hypothalamus, ventromedial, and ventrolateral prefrontal cortex were significantly reduced in anxious children and adolescents who requested that their caregiver accompany them in the scanner room compared to those without their caregiver in the scanner room. Mean activity in these regions in anxious children and adolescents with their caregiver in the scanner room was comparable to that of healthy controls. These data suggest links between social contact and neural mechanisms of emotional reactivity; specifically, presence of caregivers moderates the increase in anxiety seen with stressful stimuli. Capitalizing on the ability of anxious youths to manifest low levels of anxiety-like information processing in the presence of a caregiver could help in modeling adaptive function in behavioral treatments
